The BR-X2 Tourbillon Micro Rotor features a skeleton dial, with a tourbillon at 6 o'clock. For those unfamiliar with horology, a tourbillon is an additional device in a watch that works to counter the effects of gravity on the watch's mechanics, thereby improving its time-telling accuracy. The use of tourbillons in watches today is less for its technical use, and more for its ornamental value – it is typically employed by luxury Swiss and European watchmakers, whose customers value the craftsmanship behind tourbillons.
